Energy consumption is the biggest environmental concern with cement and concrete production. Cement production is one of the most energy intensive of all industrial manufacturing processes. Including direct fuel use for mining and transporting raw materials, cement production takes about six million Btus for every ton of cement (Table 2).

The majority of all cement shipments, approximately 70 percent, are sent to readymix concrete operators. The rest are shipped to manufacturers of concrete related products, contractors, materials dealers, oil well/mining/drilling companies, as well as government entities. The domestic cement industry is regional in nature.
Excess free lime, for example, results in undesirable effects such as volume expansion, increased setting time or reduced strength. Several laboratory and online systems can be employed to ensure process control in each step of the cement manufacturing process, including clinker formation.
Sep 30, 2011· Cement industry workers are exposed to various dusts, such as limestone, cement, coal, silica, and gypsum. Among them, cement and limestone dust are the main components of exposed dusts. Manufacturing cement can be divided into two major parts: quarrying of the limestone and cement production.

cement production plant workers. It is noted that these workers can be exposed to the raw materials of cement production, which include limestone, chalk, clay and shale, to clinker, as well as to Portland cement dust. The exact nature of the dust exposures experienced by cement plant workers has not been characterised in any of the studies.

dealt with are dust, carbon dioxide CO2, nitrogen oxides (NOx) and sulphur dioxide (SO2). This paper deals with the review of the main environmental issues related to the cement production in Europe. Key words: cement, cement industry, emissions. Introduction. Concrete is the most common construction material used in building industry. Cement
The environmental impact of concrete, its manufacture and applications, are effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the primary producers of carbon dioxide, a potent greenhouse gas.
BACKGROUND: Dusts containing crystalline silica are generated in mining, construction, glass, granite and concrete production industries. The association between exposure to low levels of concrete dust containing crystalline silica and reduction in lung function, was evaluated in a crosssectional study.
The cement industry produces about 10% of global manmade CO 2 emissions, of which 60% is from the chemical process, and 40% from burning fuel. A Chatham House study from 2018 estimates that the 4 billion tonnes of cement produced annually account for 8% of worldwide CO 2 emissions.
Cement kiln dust (CKD) is a finegrained solid byproduct generated during the cement manufacturing process and captured by the facility''s air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process.
